Cython does that in general, sure. However, this ticket is about a specific case where string methods (which are implemented in C) are slow when called from Python. Antoine found out that the main overhead is not so much from the method lookup itself but from argument parsing inside of the function. The unpacking code that Cython generates for the equivalent Python signature would speed this up, while keeping or improving the compatibility with Python call semantics.
